Key points

Free Maintenance
No glycol, simple structure. No annual and periodical check-ups or maintenance is necessary. Blind sleeve design, no pollution, no-leaking heat pipe, easy installation. No water in vacuum tubes, one broken tube will not affect the function of the whole system.

High Performance
With the cutting-edge vacuum-tube collecting technology, over 92% of sunshine energy is converted to thermal energy for heating and no circulation loss. Thicker insulation layer, functioning well in winter, even in minus-30-degree environment.



High Reliability
System is simply working with the city net water, without pumps. Inner tank made by stainless steel SUS316-1.2mm. Working with high pressure, directly connected to running water, automatically functioning. With T/P valve and exhaust valve, it protects the tank from shrinking.

Year-round Operation
With the freezing-proof technology, the system is designed and installed to operate for all seasons. Electric heater is optional to use, to ensure plenty hot water in rainy days.

Vacuum tubes are directly connected to the tank, low heat loss. Blind sleeve design and SUS316 inner tank is suitable for poor quality water supply area. Aluminum alloy frame is optional. Install angle(degree): 30/45. Pipe location on the tank is optional. It’s cheaper than split pressurized system.
